With so many options, travelers often ask: Should you visit the famous Blue Lagoon, the stylish Sky Lagoon, or explore something off the beaten path? Each lagoon offers a distinct atmosphere, from luxury spa treatments to quiet, rustic pools in the countryside.

Choosing the right one can shape your entire trip. Whether you’re after healing minerals, dramatic views, or authentic Icelandic charm, this guide will help you decide which lagoon best suits your travel style.

Let’s explore the top geothermal spots to soak, relax, and recharge in Iceland.

What Makes Iceland’s Lagoons So Special?

What makes Iceland’s lagoons so special is the way they combine Iceland’s natural wonders with comfort and tradition. From the milky blue water of the Blue Lagoon's location to the oceanfront serenity of the Sky Lagoon's water, each site is more than just a place to soak—it’s an experience.

The Blue Lagoon experience includes mineral-rich hot springs, soothing body scrubs, and modern changing rooms or even a private changing room for extra privacy. The Sky Lagoon also impresses with a better Sky Lagoon layout that includes a unique turf house and access to both cold plunge pools and warm waters facing the Atlantic Ocean. Clean, heated changing rooms and optional private changing facilities add to the comfort.

Whether you're doing a rejuvenating body scrub or moving from cold plunge to hot soak, Iceland’s lagoons offer more than relaxation—they're a luxurious way to enjoy raw nature in style.

Blue Lagoon – The Iconic Classic

The Blue Lagoon is Iceland’s most iconic geothermal spa—and for good reason. Located just 20 minutes from Keflavík Airport, the Blue Lagoon's location makes it a perfect first or last stop on your Iceland adventure. The spa is built into a lava field and filled with mineral-rich milky blue water, known for its healing properties, especially for skin conditions like psoriasis. The signature Blue Lagoon experience includes silica mud masks, a swim-up bar, in-water massages, and access to luxurious changing rooms and even private changing facilities for added comfort.

The lagoon is fed by nearby hot springs, and the temperature stays around 37–39°C (98–102°F), making it perfect year-round. Visitors can enjoy a full wellness ritual that includes a body scrub, steam rooms, and a cold plunge to awaken the senses.

While it can get crowded and is often considered touristy, the Blue Lagoon remains unmatched for its convenience, atmosphere, and amenities. It’s a full-service destination with onsite dining, skincare products, and even a hotel. Whether you're a first-time visitor or a returning guest, soaking in the milky blue water surrounded by volcanic rock is a must-do Icelandic experience that continues to capture the world’s imagination.

Sky Lagoon – A New Coastal Experience

The Sky Lagoon offers a fresh take on the classic geothermal spa, blending luxury with raw Icelandic landscapes. Perched on the edge of the Atlantic Ocean, its signature infinity-edge pool provides sweeping ocean views that are especially dramatic during sunrise or on stormy days. The lagoon’s design draws inspiration from Icelandic tradition, featuring a turf house and natural stone constructions that complement the rugged coastal surroundings.

The experience centers around a unique seven-step ritual: start with dry sauna, then steam room, followed by a cold plunge, and finally into the warm Sky Lagoon's water, all designed to detoxify and invigorate the body. Heated changing rooms and private changing facilities help maintain comfort and privacy throughout your visit. Unlike the bustling Blue Lagoon, Sky Lagoon aims for a more intimate, upscale feel—think fewer crowds and a serene atmosphere.

Add-ons include massages, body scrubs, and a swim-up bar positioned to overlook the sea. If you’re seeking a better Sky Lagoon experience—more tranquility, less commercial buzz—this is it. The blend of geothermal wellness, ocean breeze, and thoughtful architecture makes Sky Lagoon a must for travelers craving ambience and intentional relaxation.

The Sky Lagoon: Pros and Cons

Pros of the Sky Lagoon

• ✅ Breathtaking ocean views: The infinity-edge pool faces the Atlantic Ocean, offering unmatched scenery

Drawbacks: of the Sky Lagoon

• ❌ Limited accessibility: Located just outside Reykjavík, but not as close to the airport

If you’re after a better Sky Lagoon vibe—elegant, scenic, and peaceful—this is a standout choice.

Which Offers Better Value?

Sky Lagoon and Blue Lagoon have similar base prices (roughly $87–110). However, Sky Lagoon stands out for value: its basic pass typically includes the seven‑step ritual (sauna, steam, cold plunge, salt scrub), while a comparable Blue Lagoon ticket only covers a drink and silica mask. Many visitors feel Sky Lagoon's atmosphere, design, and amenities—like private changing upgrades—provide a more relaxing, spa-like experience worth the cost.

Blue Lagoon does offer iconic milky‑blue water, lava‑field ambiance, and convenience near Keflavík Airport . Yet many say you pay a premium for prestige, not substance.

Other Notable Lagoon Options to Explore in Iceland

While the Blue Lagoon and Sky Lagoon dominate most travelers’ itineraries, Iceland boasts a wealth of lesser-known geothermal pools that offer equally magical—and often more authentic—experiences. From rustic natural baths to luxurious hidden gems, these alternative lagoons provide unique settings, fewer crowds, and often lower prices.

Here are some of the best options to consider for your Icelandic adventure.

1. Secret Lagoon (Gamla Laugin) – The Original Geothermal Pool

Located in the small village of Flúðir along Iceland’s Golden Circle, the Secret Lagoon holds the title of the country’s oldest swimming pool, dating back to 1891. Unlike its more commercialized counterparts, this lagoon retains a charmingly rustic vibe, with steam rising naturally from the surrounding hot springs.

The water temperature hovers around 38-40°C (100-104°F), making it perfect for a relaxing soak after exploring nearby attractions like Geysir and Gullfoss. At roughly half the price of the Blue Lagoon, it’s an excellent budget-friendly alternative.

2. Mývatn Nature Baths – The Blue Lagoon of the North

Often called the "Blue Lagoon of the North," the Mývatn Nature Baths offer a similar milky-blue geothermal experience but with far fewer crowds. Situated in Iceland’s volcanic northeast, the lagoon’s mineral-rich waters are renowned for their skin-healing properties, while the surrounding lava fields and steaming fumaroles create a surreal, moon-like landscape. The admission fee is significantly lower than the Blue Lagoon’s, and the on-site café serves delicious Icelandic rye bread baked in the hot springs.

3. GeoSea Geothermal Sea Baths – Where Hot Springs Meet the Arctic Ocean

Perched on a cliffside in the charming whale-watching town of Húsavík, GeoSea is one of Iceland’s most unique lagoon experiences. Unlike other pools fed by freshwater springs, GeoSea’s waters are drawn from geothermal seawater, rich in minerals and warmed naturally by underground volcanic heat.

The infinity-edge design offers breathtaking views of Skjálfandi Bay, where you might even spot whales breaching in the distance. Open year-round, it’s particularly magical at sunset or under the Northern Lights.

4. Forest Lagoon (Skógarböð) – A Hidden Oasis Near Akureyri

Nestled in a birch forest just outside Akureyri, the Forest Lagoon is one of Iceland’s newest geothermal attractions, blending modern design with natural tranquility. The lagoon’s tiered pools overlook the Eyjafjörður fjord, offering stunning views of snow-capped mountains. With fewer visitors than the Blue or Sky Lagoons, it’s an ideal spot for those seeking peace and privacy. The on-site bistro serves locally sourced dishes, making it a great place to unwind after a day of exploring North Iceland.

5. Laugarvatn Fontana – A Geothermal Lagoon with a Side of Rye Bread

Located on the shores of Lake Laugarvatn along the Golden Circle, Laugarvatn Fontana is a low-key alternative to the more famous lagoons. Its series of warm pools, steam rooms, and a lakeside sauna provide a traditional Icelandic spa experience. The real highlight? The chance to taste hverabrauð, a traditional rye bread baked underground using geothermal heat.

6. Krauma – Where Fire Meets Ice

Fed by Europe’s most powerful hot spring, Deildartunguhver, Krauma combines geothermal relaxation with sleek Nordic design. Located near Reykholt in West Iceland, the lagoon features five warm pools of varying temperatures, plus a cold tub (refreshed with water from a nearby glacier). The minimalist wooden architecture and serene atmosphere make it a perfect stop for travelers exploring the Snæfellsnes Peninsula.

How to Decide: Key Factors

When comparing Iceland’s most popular spa experiences, the Sky Lagoon vs Blue Lagoon question is one many travelers face. While both offer warm water, breathtaking design, and rejuvenating soaks, the better choice depends on what you value most—location, atmosphere, amenities, or authenticity. Here’s how to decide.

Location and Accessibility

The Blue Lagoon is conveniently located on the Reykjanes Peninsula, just 20 minutes from Keflavík Airport. It’s ideal for travelers looking to unwind immediately after a flight or before heading home. The Sky Lagoon, on the other hand, is nestled closer to Reykjavík’s city center—perfect if you’re already exploring the capital and want to visit Sky Lagoon without much travel.

Atmosphere and Design

Both spas are known for their stunning visuals. The entire lagoon at Blue is surrounded by black volcanic rock and filled with soft blue water, offering a surreal, otherworldly atmosphere. In contrast, Sky Lagoon feels like a sanctuary rooted in Icelandic tradition. Its infinity pool and infinity edge overlook the Atlantic Ocean, creating a peaceful, nature-blended design. The grass roof covering its turf house adds to its rustic appeal.

Wellness Rituals and Features

A key difference in the Sky Lagoon vs Blue Lagoon comparison lies in what’s included. The Blue Lagoon offers a silica mud mask, free drink, and access to mud masks, saunas, and steam rooms. However, some say it feels more commercial, partly because it uses excess water from a power plant nearby.

Sky Lagoon shines with its signature seven step ritual, which includes a cold mist, sauna, cold plunge, steam, exfoliating scrub, and more—all included in most ticket options. Many feel this provides better value, especially for those seeking a true spa experience.

Changing and Comfort

Both locations offer private changing facilities, stylish locker rooms, and modern infrastructure. You won’t need to worry about privacy or cleanliness. Whether you’re wrapping up after a dip or preparing for dinner at an onsite restaurant, both facilities make it seamless.

Hair and Skin Concerns

Worried about getting your hair wet? Both spas contain mineral-rich water, which is great for your skin but can be drying for hair. Blue Lagoon’s high silica content is particularly harsh. Most guests apply conditioner before entering the pool, especially at Blue.

Nighttime Magic and Seasonal Perks

Want to soak under the stars and chase the northern lights? Both lagoons offer this magical experience in winter. The steam rising from the warm water, the glow of blue water, and the hush of a clear Icelandic night combine for a breathtaking moment.

Food, Drink, and Extras

Looking to enjoy a few drinks while soaking? Both locations have swim-up bars. The Blue Lagoon includes one free drink with some tickets. Each also has a restaurant onsite, ideal for extending your visit into a relaxing half-day.

Other Options to Consider

If neither feels quite right, Mývatn Nature Baths in the north or pools along the Golden Circle may appeal to those seeking simpler, naturally heated settings.

FAQs

Is Sky Lagoon or Blue Lagoon better for first-time visitors?

Both offer incredible views and warm waters, but it depends on your style. Blue Lagoon is iconic and built around dramatic black rocks and intense geothermal activity.

Yes, all locations allow you to purchase drinks—sometimes right from the pool. Each also has a spa restaurant. It makes sense to eat after soaking!

Is there a cheaper option with fewer crowds?

Myvatn Nature Baths in the north offer a more relaxed vibe, slightly less polished, but shaped by volcanic activity. It’s feet deep in warm water and has its own way of charming visitors. Many recommend visiting if you're road-tripping Iceland.

Conclusion
